Travel and Terrain Advice
At the moment, the risk of avalanches is low, but the risk level will increase in the later snowfall situation. It is forecast that snowfall will intensify when the front passes during the day. Pay attention to its snowfall intensity and condition with the old snow surface. Even a very small avalanche will scoop up your feet. If a terrain trap is added to it (for example, a cliff below or a glide crack), it will have a serious ending. The possibility of rain is suggested at very low elevations. In that case, do not approach slopes with glide cracks.
